HTTP and HTTPS

HTTP stands for Hypertext Transfer Protocol, while HTTPS stands for Hypertext Transfer Protocol Secure. HTTP is the protocol used to transfer data between web servers and web browsers, while HTTPS is a more secure version of HTTP that uses encryption to protect data transmitted over the connection.

HTTP is not secure, which means that any data transmitted over an HTTP connection can potentially be intercepted and read by third parties. HTTPS is much more secure than HTTP, as the encryption used by HTTPS makes it difficult for third parties to intercept and read data transmitted over the connection.

Google has announced that it will mark all HTTP pages as "not secure" in its Chrome browser starting in July 2018, which means that having an HTTPS site is important for SEO.

Having an HTTPS site can also improve user trust and confidence, as users are more likely to feel secure and protected when browsing an HTTPS site.
